Cribl·Software Engineer·Onsite - System Design / Architecture
Jun 2026
System design round at Cribl for a software engineering role. The whole interview was basically one big open-ended question about log parsing pipelines, which sounds narrow until you realize they want you to cover everything from schema inference to privacy to scaling. Felt like a platform eng interview dressed up as an ML question.
- Design a production system that uses an LLM, optionally combined with deterministic parsers, to convert raw log messages in heterogeneous formats into structured JSON. Walk through architecture, data flow, schema inference, extraction strategy, validation, scaling, reliability, monitoring, privacy considerations, and how you'd evaluate quality.
“This one is deceptively wide.”
